THERE IS NO SIZE TAG; PLEASE CHECK MEASUREMENTS CAREFULLY!

I believe this is a vintage L but probably fits a modern S/M.

Great reversible jacket with pink and white candy stripes on one side with angled side pockets, and white on the other side with square pockets. Chrome metal snaps.  White hood zips into collar. The only tag I can find is inside the right angled pocket and reads Izzi New York.  There are no material content or size tags.
